Summary

This study tested a combination of two drugs, ibrutinib and obinutuzumab, in 54 adults with chronic lymphocytic leukemia (CLL) that had come back or stopped responding to treatment. The main goal was to check safety and find the best doses. Researchers also looked at how well the drugs shrank cancer. This is an early-phase trial, so results help guide future studies.
